Digitalize Safety Requirements, IPLs, SIF and more
- Safety Requirements Specification (SRS)
To conform with standards like IEC 61511 (process industry) or IEC 62061 (machinery sector), you will need to develop a consistent and complete Safety Requirements Specification (SRS). With a range of different industry experiences we have adopted best-in-class data-centric tools and templates to ensure your project remains on the right track. - IPL and SIF Management with Cause & Effects (C&E)
Provide your LOPA reports and we will enter all your Independent Protection Layers (IPL) credited with risk reduction into our tag-based database. This data can include all the credited Alarms, BPCS trips, Interlocks, Relief Valves and SIF. If you provide Cause & Effect (C&E) diagrams, we can also enter the C&E into our database and auto-generate unit operation C&Es to manage in this environment going forward. - SIL Verification Calculations
After completing a proposed design for a Safety Instrumented Function (SIF), the achieved average Probability of Failure on Demand (PFDavg) or Probability of Failure per Hour (PFH) must be calculated. Our specialists will support you through all the complex requirements to demonstrate that your design can achieve the target SIL. - Validation Test Plans
All Safety System projects reach a stage that requires physical system testing, and this needs advanced planning to get optimum results without costly re-work. Our digitalized approach to the development of validation plans will help your project to succeed at the vital stage of system testing. - Proof Test Procedures
After some time in operation all Safety Systems need to undergo proof testing at the interval determined by the SIL verification. This testing needs to be carried out with a practical and detailed procedure to achieve consistency and complete coverage. Our specialist digitalized approach to functional safety will ensure your proof test procedures are of the highest quality.

Management, Planning, Assessment & Training
- Functional Safety Management, Planning & Procedures
Projects involving Safety Integrity Level (SIL) rated safety instrumented systems (SIS) need the correct setup to achieve good quality outcomes. Our decades of experience with SIL-related projects can give you the advantage of not making the mistakes we have seen others make when it comes to planning, procedures and competence of personnel setup. Whether it's reviewing your current procedures or writing new procedure and plans. - Functional Safety Assessment (FSA) and Audit
The earlier your project plans for functional safety assessment (FSA), the better the outcomes will be. Appoint an experienced FSA leader with the right level of experience and practical knowledge, and ensure your SIL project remains on track. After some time in operation, complete an audit using one of our specialist checklists, either with your own experts, or with eFunctionalSafety guiding the way. - Training

Hazard, Risk and SIL Studies
- Hazard and Risk Analysis
Expert facilitation for a Hazard and Operability study (HAZOP), ensuring that the correct information is developed to support later stages of the safety lifecycle. Our facilitators can follow any industry-recognized method, including HAZID, HAZOP, SWIFT, Checklist or FMEA. Whether it's using your procedure, or producing one for you, our experts come with years of experience and their own specialist software tools to deliver a quality outcome. - Layer of Protection Analysis (LOPA)
Our LOPA service starts with developing a terms of reference (TOR) to ensure everyone is clear on the process and sufficient information is available to proceed. After the TOR is approved, we move to facilitating the LOPA workshop, either face-to-face or remotely. We produce detailed LOPA reports that detail all the assumptions, list of credited independent protection layers (IPL) and SIL targets for any identified safety functions. - Fault Tree Analysis (FTA) / Event Tree Analysis (ETA)
When the need arises, our specialist service extends to developing custom fault trees and event trees to help with the more difficult-to-demonstrate event scenarios or safety functions.
